they do hurt for a few days, particularly if the skin stretches. I've had moles removed on three different occasions and I haven't ever had to keep the bandage on... for the first 24 hours I kept it dry but after that I showered normally. (one on my tummy, two on my back and one on my breast)

I guess follow your Dr's instructions but if it gets hot or really really sore take the bandage off. GL
